QUESTION
Class QgsVectorlayer
derives from base class QgsMapLayer
which derives from base class QObject
. I want to cast a QgsVectorlayer
object to a base class. This should easily be possbile but I get an error and don't understand why.
The annex to the (probably not unimportant) error message is:
...qgsgeometry.h:46:7: note: 'QgsVectorLayer' is incomplete
Line 46 contains only the QgsVectorLayer
class definition:
ANSWER
Answered 2022-Apr-14 at 12:13The definition of the class is missing at the point where the static_cast
is used. Just because the definition of the class exists in some header file doesn't mean that the compiler automatically knows it everywhere the class is referenced. Whichever header file defines this class was not #include
d, so the only thing that the compiler knows is that the class has been declared.
Line 46 contains only the QgsVectorLayer class definition:
class QgsVectorLayer;
The translation unit #include
d this header file, directly or indirectly.
The definition of QgsVectorLayer:
class CORE_EXPORT QgsVectorLayer : public QgsMapLayer, public QgsExpressionContextGenerator, ... {...}
And this header file was not #include
d, directly or indirectly.
You'll need to figure out how to correctly #include
the required header files.
QUESTION
First time I write a question on stackoverflow, after more than 5 years using it ! Hopefully I did not miss the answer in another post and that I'll meet the standards expected to ask a question:
I am trying to dynamically move text in a MS-word document based on a user input, using Headings to find what to move and where to move it.
For the sake example let's say my document is organized like this:
Section 1 Section 2 Section 3 Annex 1
With "Section 1", "Section 2", "Section 3" and "Annex" being defined as Headings 1 style.
In each Sections (and annex) you have a mixed batch of text, tables, pictures, etc.
Let's assume users get asked the following question through VBA (triggered either via a button click event or document open event, does not matter - this I know how to do). Depending on their answer, I would like to either
a) do nothing
b) do the following actions:
select the entire "Section 1", including Heading and all the text, figures, tables, etc, in it (in other words - until "Section 2" starts)
move it between Section 3 and Annex 1 so that the document structure now looks like this: Section 2 Section 3 Section 1 Annex 1
ANSWER
Answered 2022-Mar-30 at 08:20You are on the right lines but need to avoid using the Selection
object. There are rare circumstances when using Selection
is unavoidable but this isn't one of them.
Word has a number of hidden predefined bookmarks, one of which returns the full range of a heading level. This is used in the GetHeadingBlock function below.
A Range
also has a FormattedText
property that can be used instead of the clipboard.
QUESTION
I've been puzzling over Technical Standard 51's Annex C and Annex 29 on Unicode Text Segmentation as well as the Unicode Grapheme Break Test data file and it appears that the definition of a cluster in Annex 29 does not cover the sequence tag_base tag_spec+ tag_end which means that characters built as Emoji tag sequences like 🏴 will be treated as 7 graphemes by the Annex 29 algorithm rather than a single grapheme as one would expect.
I understand that there is flexibility in precisely which sequences are rendered by an implementation, but it seems like the correct behavior would be to treat all instances of syntactically valid Emoji tag sequences as single graphemes for cluster analysis rather than to break up characters built from tag sequences into multiple graphemes.
Edited to add:
- Is this an oversight in annex 29 on text segmentation?
- Should an implementation of text segmentation treat a tag sequence like 🏴 as a single grapheme or as seven graphemes?
ANSWER
Answered 2022-Mar-23 at 12:37The invisible tag characters belong to the grapheme cluster break category Extend
, meaning they behave just like a combining mark. There doesn’t need to be a special case for handling emoji tag sequences because grapheme cluster breaking rule GB9 will simply take care of them.
QUESTION
I'm following up on a previous question:
I have the following schema:
...ANSWER
Answered 2022-Mar-08 at 13:25It seems as if FromSchema cannot handle a union of the schemas. You can get around this by turning the union into a tuple, converting each schema in the tuple with FromSchema, then converting it back to a union.
For this we will first need the excellent holy grail of a post in How to transform union type to tuple type
I've renamed TuplifyUnion
to UnionToTuple
here.
Let us then write a type that converts a union of schemas we wish to transform.
We need to convert this union to a tuple, then convert each of the schemas separately, and finally turn the resulting tuple back into a union.
QUESTION
I trying to get the RSA signature as described in Annex A2.1 of EMV book 2. As I understand it was described in ISO9796-2 as scheme 1, option 1. So, the resulting signature should contain a Header equal to '6A' and a Trailer equal to 'BC'.
The algorithms ALG_RSA_SHA_ISO9796 and ALG_RSA_SHA_ISO9796_MR are the only suitable that I could find. But they acting like scheme 1, option 2 with a Trailer equal to '33cc'
Is it possible to get a signature with Trailer = 'BC'?

Answered 2022-Feb-24 at 10:46You can generate such signature using Cipher.ALG_RSA_NOPAD
in decrypt mode.

QUESTION
I have been recently struggling to understand the meaning of a DIR file in Emv book 1. I dig a lit bit and I find that my perspective of a folder got me to the wrong path. For me a 'Directory' is equal to a 'folder' that contains only other elements. So when I was going through Emv specifications they said after selecting a DDF or an ADF it sends back the FCI. So I was confused as I was seeing DDF and ADF just as folders so where they store FCI's data . I get more confused when I read "Directories are optional within an ICC".
Can someone please explain to me what is a Directory in ICC and what is the difference between a DDF and its related DIR A that exists in all examples of the section : "Annex C Examples of Directory Structures" of emv book 1 Thank you.
...ANSWER
Answered 2022-Jan-27 at 13:41Can someone please explain to me what is a Directory in ICC.
EMV card file structure is based on ISO/IEC 7816-4. You better read it first. There you can find detailed description of many terms you are talking about. Generally, there are two types of card files: DF (dedicated file) and EF (elementary file). EF cantains binary data. DF can contain any file. Every file (both DF and EF) can be selected with APDU SELECT. Every selected file can send as a response FCI structure -- data with general information about this file (type, size, attributes and so on).
what is the difference between a DDF and its related DIR
EMV book 1: "The DIR file is an AEF (in other words, an EF) with a record structure according to this specification including the following data objects according to ISO/IEC 7816-4. ..."
DDF and ADF are subtypes of DF. An ADF is the entry point to one or more Application Elementary Files (AEFs). A DDF is an entry point to other ADFs or DDFs.
QUESTION
I couldn't find any sources speaking about the next point in specification (let it be GlobalDeclarationInstantiation):
ii. If replacing the FunctionDeclaration f with a VariableStatement that has F as a BindingIdentifier would not produce any Early Errors for script, then
I don't understand this step, what would it be demonstrating this error?
I am trying to figure out this step in annex. So if we don't do replacements FunctionDeclartion with the VariableStatement, we won't get the error. Conversily we will get the error, if we do this replacements. What is example of it then?
...ANSWER
Answered 2022-Jan-23 at 01:37The only of the Script early errors that I can see possibly applying to that replacement is
It is a Syntax Error if any element of the LexicallyDeclaredNames of
ScriptBody
also occurs in the VarDeclaredNames ofScriptBody
.
So let's assume the script
QUESTION
Below is a script that I am running that searches for items stored in an annex location based on the value in column 2 on sheet LX03SB. We currently have 10 annex locations so I added a search for each one, but as we expand this is becoming more and more tedious. Is there a way to modify the valueToWatch function to find any value that starts with Annex instead of needed Annex01, Annex02, etc.
...ANSWER
Answered 2022-Jan-23 at 00:17I believe your goal is as follows.
- You want to reflect the script for searching the values like
Annex01
,Annex02
and so on from the column "B" of "LX03SBD" sheet in your script.
In this case, how about using TextFinder? When this is reflected to your script it becomes as follows.

is the gcc default. It enables optimisations which assume no-rounding IEEE arithmetic. -frounding-math
turns these optimisations off. The switch itself does not change the rounding behaviour, and thus does not change whether the macro is defined.
